-11 Claims.

This invention'relates to locks and hasps .especially of a type suited for fastening the lids of trunks and articles of luggage, and particularly of a construction employing a loop form of .hasp member.

One object of the invention is to prevent the release of a loop form of hasp member from engagement with a draw shoulder by the use ofa lock which is located in a manner to be straddled by the arms of the hasp member particularly where the hasp member .is materially thinner than the depth of the lock case and it is desired to cover and conceal the .bolt of the lock.

Another object is to avoid the necessity for providing a keeper separate from the parts which stamping, bending or drawing thereby to lower the cost of production.

The foregoing and other objectives are referred to in greater particular i the following description of an illustrative embodiment of the invention in which reference is had to the accompanying drawings wherein:

The parts of Figs. '7 to 14, inclusive, comprise .all of. the parts that are necessary to be assembled to form a complete lock and hasp structure incorporating the present improvements. The hinge abutment,.illust rated herein in the form of housing In .is provided with .tongues -II which project through slots l2 in the mounting plate l3 and sufiiciently therebeyond to have their extremities swaged or peened over permanently to holdfparts l0 and I3 together. By this means the hinge bar M of the loop-like hasp member [6 is pivotally anchored at the front or rounded, closed end ..I'|. of notches H3 in the side walls of housingv I0, being yieldingly pressed thereagainst by the two leaf springs I9 which .are secured by rivets 2| to the mounting plate I3 which is adapted to abut fiatly against the front surface of the .lid of a trunk or the like to which it, maybe secured as hereinafter referred to.

Hinge bar IA of the hasp member carries a lug 24 for cooperating withsprings l9 to effect a detent .action and this lug may be formed by the shape to which the hasp member is blanked out of sheet metal, the portions 25 of the hinge bar I4 being swaged. into a round cross sectional shape for afiordinga smootherpivot for the hasp member within the notches [8. The nose portion of the hasp member is preferably thinner than thedepth of the lock case by an amount at least equal. to the thickness of a lock bolt 38 hereinafter more fully referred to and includes a carried.block-like section 26 backed by the notch 21 which receives this look. bolt so that the latter is covered and concealed by said blocklike section of the -nose portion of the hasp member. The block-like sectionfZfimaybe spot welded or .otherwisemountedon and made rigid ness of the hasp member as well as ofiset to the rear of the total depth of lock case 32 in Fig. 3. Lug 28 is received into a square aperture 29 in the mounting plate 3| for the lock case 32. The

latter has tongues 33 which enter and fit slots 34 in the mounting plate 3| and project at the rear thereof sufliciently to be swagedor peaned over to hold the lock case 32 and mounting plate 3| permanently together. The lock case 32 is notched at 36 to accommodate the nose section 26 on the hasp loop so that the frontmost face 3! of the keeper block 26 may fall approximately flush with the front surface of the lock case.

Contained within the lock case are the working parts of the lock mechanism including the platelike bolt 38, the pawl 64 and the key barrel 4| shown respectively in Figs. 12, 13, and 14. The bolt plate 38 has an elongated aperture 42 through which extends the key barrel 4| the latter being journaled by means of its end 43 of reduced diameter in a hole 44 in mounting plate 3 The front end 46 of the key barrel is journaled in the keyhole 48 in the .front wall 49 of lock case 32 and the key barrel as a whole is retained by its flange 5| which occupies a counterbore 41 in said front wall of the lock case at the rear of the keyhole. In usual fashion the key (not shown) is inserted through keyhole 48 and through the configured slot 52, its working edge engaging the notch 53 in bolt plate 38. The latter has an elongated slot 54 and an elongated notch 56 in line therewith each respectively engaged and guided by the short pin 51 and the long pin 58 which are fixedly mounted on plate 3|. This plate contains at its top edge a recess 59 to receive the dowel tongue 22 which enters thereinto back of the edge 6| of the lock case which flatly abuts against the front surface of mounting plate 3 l.

The bolt plate 38 also carries the lug 62 which cooperates with a finger 63 projecting from pawl 64, the latter being loosely pivoted on long stud 58 by means of its hole 66. The concave portion 61 of the edge of pawl 64 is adapted for coaction with the working edge of the key. In the heel 68 of pawl 64 is tightly anchored one end 69 of a leaf spring whose free end bears against the inside surface of the edge wall 12 of the lock case constantly causing pawl 64 to be urged counterclockwise or toward the bolt lug in Figs. 4 and 6. Two holes 13 in mounting plate |3 and three holes 14 in mounting plate 3| accommodate screws or rivets (not shown) for fastening these plates interchangeably and respectively to the cover and body of a trunk or other piece of luggage.

In operation, the lid of the trunk or other piece of baggage carrying plate I3 is closed against the body of the trunk in the usual way whereupon dowel tongue 22 enters recess 59 thus accurately aligning the side walls of the hinge case I6 and lock case 32, sothat the hasp member l6 may be swung downward from its position in Fig. 5 to its position in Fig. 1. This presents the keeper notch 21 to the lock bolt 38 which may then be shot into engagement with the keeper 28 by turning a key in barrel 4| thus shifting the parts from their positions in Fig. 4 to their positions in Fig. 6. This, by concealed means inaccessible except by use of the key, makes it impossible to swing hasp member l6 away from the position in which its arms straddle lock case 32 and detains the curved nose of the hasp member engaged with its draw shoulder formed by the correspondingly curved bottom end of the lock case. The parts present a fiush and smooth appearance when thus locked, the front portion of keeper block 26 nicely filling the lock case opening 36. This is in part made possible by the described relative dispositions and dimensional relationships of lock case 32,1ock bolt 38, hasp nose section 26 and keeper structure 28.

- Some of the advantages of these improvements may be obtained by the use of parts differing from those herein disclosed in shape and arrangement, as for instance the loop-like hasp member may be swung from a toggle action lever capable of causing the nose loop of the hasp member to draw very tightly against its draw shoulder, and'such toggle action lever, instead of the hasp member itself, may be engaged by the lock bolt and thereby prevented from swinging open. Also the draw shoulder may be comprised of a part separable from the lock case. These and other departures from the preferred embodiment herein disclosed, together with all fair equivalents which come within the definitions of the appended claims, are

intended to be included and covered within the scope of the claims.

I claim:

1.
